BMW F 850 GS (2018+, including Adventure) Maintenance Schedule and Service Intervals

2018 2019 2020 BMW F 850 GS black LHS studio diagonal

This is the maintenance schedule and service intervals for the BMW F 850 GS, BMW’s middleweight adventure motorcycle, made from model years 2018 onward. It’s the same maintenance schedule for the BMW F 850 GS adventure (the GSA).

The BMW F 850 GS was announced at the same time in late 2017 for the 2018+ model year.

It was announced at the same time as an upgrade of the lower power, more road-oriented bike with a detuned version of the same motor, the BMW F 750 GS.

The new F 850 GS is powered by a liquid-cooled 4-valve 853cc parallel twin with a 270-degree crankshaft. It makes 70 kW (95 hp) at 8,250 rpm, a roughly 10% upgrade over the previous BMW F 800 GS from which the new bike has taken the mantle.

In mid-2020, the BMW F 850 GS received a few new updates, including standard ABS Pro and DTC (previously an option), LED turn indicators, and a USB port.

About the BMW F 850 GS

The BMW F 850 GS is BMW’s middleweight travel enduro motorcycle. It’s sometimes seen as the smaller alternative to the BMW R 1250 GS, but the truth is that because of its different motor, lighter weight, and unique personality, it’s just a very different motorcycle.

It’s an update to the BMW F 800 GS, but there’s much more to it than a name change — and much more to it than even the new engine, though that’s a big part of it.

The core of the BMW F 850 GS is the 853cc liquid-cooled parallel twin engine. It makes a peak of 70 kW (95 hp) at 8,250 rpm, with peak torque of 92 Nm at 6,250 rpm, neither low nor high.

The power band of the F 850 GS means that you can use it anywhere in the rev range. It’s geared so that you can do low-speed work when you need to, but also cruise effortlessly along the highway using its cruise control.

One significant change in the F 850 GS vs the previous model is that the engine nos has a 90 degree journal offset and a 270 degree firing order.

This 270-degree parallel twin design gives the engine a different torque characteristics and a raspier sound that some say is similar to that of a 90-degree V-twin engine.

The engine has two counterbalance shafts in front of and behind the crankshaft, driven by spur gears from the left of the crankshaft. These give the new engine a much smoother personality than the outgoing block.

There have been many enhancements to make the BMW F 850 GS more rideable and usable in everyday life. These include

  • A self-amplifying anti-hopping wet clutch. This is both easier to use at the clutch lever, and also helps with using the friction zone, e.g. while braking or down-shifting.
  • A quick shifter, which BMW calls “Gear shift assistant Pro” — lets you do quick up- and down-shifting without even using the clutch.
  • Relocating the exhaust system to the right hand side, so that you can manoeuvre the motorcycle when parked from the left without risk of burning yourself

For the first time, the BMW F 850 GS has tubeless tyres. It still has a 21-inch front tyre, giving it more off-road agility than the 19-inch front tyre on its little sibling.

The BMW F 850 GS Adventure (the GSA) is the same basic bike, except with

  • A larger tank (23L vs 15L usable volume)
  • Standard crash bars
  • A taller standard screen
  • Different luggage options

Both the F 850 GS and F 850 GSA have the same long-travel suspension, wheel and tyre options, TFT display, and other options.

From 2020, BMW made ABS Pro (cornering ABS) standard across the F 850 GS and F 750 GS range, making them an even more compelling option.
